The TPS62912 and TPS62913 devices are a family of high-efficiency, low-noise and low-ripple synchronous buck converters. The devices are designed for noise sensitive applications that can normally use an LDO for post regulation such as AFEs, high-speed ADCs, Clock and Jitter Cleaner, Serializer, De-serializer, and Radar applications. The device operates at a fixed switching frequency of 2.2 MHz or 1 MHz, and can be synchronized to an external clock. To further reduce the output voltage ripple, the device integrates loop compensation to operate with an optional second-stage ferrite bead L-C filter. This allows an output voltage ripple below 10 µVRMS. Low-frequency noise levels, similar to a low-noise LDO, are achieved by filtering the internal voltage reference with a capacitor connected to the NR/SS pin.
